Mechanical Gears and Transmissions with Lego WeDo 2.0

Understanding how mechanical transmissions work is essential for building functional robotics projects. This text-based course guides you through core mechanics using Lego WeDo 2.0, helping you turn motor rotation into powerful, controlled movement. You will start with fundamental principles of force and torque before exploring various gear mechanisms. Through clear explanations and structural design principles, you will gain confidence in constructing efficient mechanical systems. What you'll learn: - Understand basic mechanical concepts including gear ratios, torque, and rotational speed - Explore spur gears, bevel gears, worm gears, and rack-and-pinion transmissions - Analyze how gear assemblies change direction and amplify force or velocity - Apply belt drives and pulley systems to transfer motion across distances - Combine mechanical transmissions with smart motors and simple control logic - Solve mechanical design problems using step-by-step written exercises. The course begins with essential terminology, structural principles, and simple gear interactions before advancing to multi-stage transmissions and compound mechanisms. This program is designed for beginners, educators, and young makers with no prior mechanics experience required. Start reading today to unlock the fundamentals of educational robotics engineering.
